Description

The version of Microsoft Silverlight installed on the remote host reportedly does not properly use unmanaged objects, which could allow a malicious web application to access memory in an unsafe manner.

An attacker may be able to leverage this vulnerability to execute arbitrary code on the affected system if a user on it can be tricked into viewing a specially crafted web page using a web browser that can run Silverlight applications.
